SSH 提示 Pseudo-terminal will not be allocated because stdin is not a terminal. 使用 -T 參數可能禁用輸出
ssh -T root@host < /path/to/shell/file cat file | ssh -T root@host
1. 使用openssl命令去掉私鑰的密碼 openssl rsa -in ~/.ssh/id_rsa -out ~/.ssh/id_rsa_new 2. 備份舊私鑰mv ~/.ssh/id_rsa ~/.ssh/id_rsa.backup 3. 使用新私鑰mv ~/.ssh/id_rsa_new ~/.ssh/id_rsa 4. 設置權限chomd 600 ~/.ssh/id_rsa
-v Verbose mode. Causes ssh to print debugging messages about its progress. This is helpful in debugging connection, authentication, and configuration problems. Multiple -v options increase the verbosity. The maximum is 3.
